Created attachment 176657 [details] mylyn/context/zip impacted classes
the problem is solved, a test have been added
now, a class can be dropped anywhere, can you confirm Saadia?
comment from Saadia: When I drop a class, which is not contained in a package, from the model explorer to a package: Graphically, the class is inside the package, but is not moved inside the package in the model explorer. Steps to reproduce: 1. Create a package in the model explorer. 2. Create a class outside the package in the model explorer, 3. Drop the class inside the package.
Now it runs. so I close the bug
